  • Patent number: 7815350
    Abstract: Headlamp systems are provided that form desired beam patterns from light supplied by semiconductor light sources. The present invention is headlamp system for a vehicle including at least one first light source, at least one second light source, and a first lens system having at least one lens operably associated with the at least one first light source to provide a spread portion of a desired beam pattern. The present invention also includes second lens system having at least one lens operably associated with the at least one second light source to provide a hot spot portion of the desired beam pattern.
    Type: Grant
    Filed: May 1, 2008
    Date of Patent: October 19, 2010
    Assignee: Magna International Inc.
    Inventors: David J. Valcamp, Ronald O. Woodward
  • Patent number: 7563009
    Abstract: The headlamp system of the present invention includes a source array of semiconductor light sources and a lens system to produce a first component, such as spread light, of desired beam patterns and a source array of semiconductor light sources and a lens system to produce a second component, such as the hot spot components, of the desired beam patterns. Light from the semiconductor light sources of each source array is transferred to the respective lens system by a transfer device comprising a series of light pipes which capture light emitted by the semiconductor light sources and emit the captured light adjacent the respective lens systems. One or both source arrays can include additional semiconductor light sources which are selectively illuminated or extinguished to provide steering hot spots in the beam pattern to illuminate areas adjacent the vehicle over which the vehicle will be turned.

  • Patent number: 7258474
    Abstract: Headlamp systems are provided that form desired beam patterns from light supplied by semiconductor light sources. The systems include a source array of semiconductor light sources and a lens system to produce the spread components of desired beam patterns and a source array of semiconductor light sources and a lens system to produce the hot spot components of the desired beam patterns. Light from the semiconductor light sources of each source array is transferred to the respective lens system by a transfer device comprising a series of fiber optic cables which capture light emitted by the semiconductor light sources and emit the captured light adjacent the respective lens systems. One or both source arrays can include additional semiconductor light sources which are selectively illuminated or extinguished to provide steering hot spots in the beam pattern to illuminate areas adjacent the vehicle over which the vehicle will be turned.
